When I boot up about half the time I notice that bios doesn't detect a primary slave or secondary master, only the primary master shows up. When I get into Windows my DVDRW and CDRW both magically appear after not being detected. It's not like this is really affecting my computer or anything, it's just that I noticed it, and usually in past experiences if it wasn't detected in bios it wouldn't be there in Windows. Am I just going crazy?
